I would go with the JL XRs(i assume you meant XRs)..why??? because I have owned them and they sounded excellent. They impressed a few people who have a much better ear than I have as well(musicians, 1 of whom does some recording work for a local college). I had them running off about 120 watts per side. I have not heard the infinities or alpines. I did have the TRs for a week while waiting for my XRs to arrive. The TRs are a good sounding speaker, but there is a night and day difference between them and the higher end XRs.
